ROUGH CUT (NO REPORTER NARRATION) STORY: Kharkiv residents and emergency workers on Sunday (February 22) rushed to the aid of protesters at a pro-Ukrainian rally when a deadly blast struck the crowd. The bomb in Kharkiv, the biggest city in the east, struck one of numerous events across Ukraine on Sunday marking the deaths of 100 protesters a year ago in an uprising that toppled a Moscow-backed president. At least two people were killed, far from eastern Ukraine's war zone, and Kiev said it had arrested suspects who had been armed and instructed in Russia. A Ukrainian prosecutor said one of those killed and four of the wounded were police who had been guarding the demonstration, and a witness told Reuters his friend, an activist, was also killed. Kharkiv is more than 200 kilometers (140 miles) from the war zone. It has occasionally seen violent protests by separatists in the past year but is now firmly under government control, and residents mostly support Kiev. Ukrainian authorities fear violence could spread from two rebellious provinces to other areas in the mainly Russian-speaking east, a swathe of territory which the Kremlin calls "New Russia". Markian Lubkivskyi, an aide to the head of Ukraine's SBU security service, said four suspects had been arrested. They were planning to conduct a series of attacks in the city with a Russian-made "Shmel" rocket launcher. Moscow did not immediately respond to the accusations. It has long denied aiding its militant sympathizers in Ukraine. Ukrainian officials initially said the blast was caused by an explosive thrown from a car, but later said a bomb had been buried under snow. The explosion follows blasts in other Ukrainian cities in recent weeks, although it appears to be the first in which fatalities were reported.
